Abstract

The present invention discloses an assembled beam-column flexible shock-absorbing joint assembly, joint structure, and construction method. The assembly comprises a column-end connector, a beam-end connector, and a hydraulic support assembly for connecting the two components. The column-end connector is mounted on the exterior of a concrete column, and a plurality of first and second hydraulic supports are disposed between the column-end connector and the beam-end connector. The beam-column joint can move slightly laterally along the beam and can also convert vertical displacement caused by shear forces into lateral displacement of the beam to a certain extent. This allows for energy dissipation during earthquakes, making the joint more reliable than conventional beam-column joints during earthquakes.

Description

Technical Field

[0001] The present invention relates to the technical field of concrete structure connection of building structures, and in particular to an assembled beam-column flexible shock-absorbing node component, a node structure and a construction method. Background Art

[0002] The construction industry is currently moving towards industrialization. Prefabricating and processing prefabricated concrete structural components in factories, then assembling and connecting them on-site using specialized connection methods, is a primary method for achieving this. Compared to cast-in-place concrete structures, prefabricated concrete structures can save energy and formwork during on-site construction, improve worker efficiency, and speed up overall construction.

[0003] Extensive prior experience indicates that prefabricated concrete structures suffer from poor integrity and seismic resistance, primarily due to problems with beam-column joint connections during on-site construction. With the increasing number of high-rise buildings, the seismic performance of prefabricated concrete structures depends heavily on the performance of their beam-column joints. During an earthquake, the seismic forces can cause high-rise buildings to sway significantly, ultimately leading to tilt and damage. Summary of the Invention

In the event of an earthquake, the beam can be translated laterally to a certain extent, and the vertical displacement occurring when the beam-column node is sheared can be converted into lateral displacement of the beam to a certain extent, thereby achieving the effect of energy consumption and shock absorption, and reducing damage to the building.

DETAILED DESCRIPTION

[0059] The following will clearly and completely describe the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0060] In the description of the present invention, it should be understood that the terms "inside", "outside", "left" and "right" indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0061] The present invention discloses Figure 1-17 The structure shows an assembled beam-column flexible shock-absorbing node structure, which applies hydraulic components and springs to the beam-column node structure, effectively enhancing the seismic performance. The structure includes a precast concrete column, a precast concrete beam, and a beam-column connection assembly connecting the two. The beam-column connection assembly includes a horizontal Π-shaped structure 10, four steel plates 9 forming a quadrangular column structure, angle plates 7 connecting adjacent steel plates, a U-shaped steel bar connector 8, a spring connection assembly consisting of a support rod 11 and a spring, a first hydraulic support 6, a second hydraulic support 5, a rotating seat 4, an outer sleeve 3, a column end auxiliary connection sleeve 2, an internal reinforcement bracket 1, 6mm bolts, 10mm bolts, 20mm bolts, a spring, and a guide tube. Each part is connected by a mortise and tenon structure or by bolts.

[0062] The Pi-shaped structure 10 comprises three parts, an upper transverse plate, a vertical plate, and a lower transverse plate, connected in sequence. The vertical plate is provided with four first circular through-holes. The thickness of the upper and lower transverse plates is greater than that of the vertical plates. The upper and lower transverse plates are each provided with a first recessed groove on their upper and lower surfaces. Vertical grooves are provided on the left and right sides of the upper and lower transverse plates, and each is provided with bolt holes for bolt fastening. A rotating seat 4 is installed in these first recessed grooves and secured thereto with bolts. A U-shaped steel bar connector 8 has a length that is the same as the width of the upper and lower transverse plates, and its ends are the same size as the vertical grooves. The open end of the U-shaped steel bar connector 8 can be secured in the vertical grooves by bolts. I-shaped grooves are provided at the upper and lower ends of the outer side of the vertical plate, respectively. The I-shaped member with the first hydraulic support 6 can be bolted into these I-shaped grooves.

[0063] The longitudinal reinforcement extending from the end of the prefabricated beam can be inserted into the U-shaped frame of the U-shaped steel bar connector 8, and the excess portion extending to the outside of the U-shaped steel bar connector 8 can be artificially bent to achieve a certain fixing effect.

[0064] The rotating seat 4 includes a semi-cylindrical seat with a through hole and a rectangular plate. Bolt holes are provided on the rectangular plate for connecting the rotating seat 4 to the upper horizontal plate or the lower horizontal plate. The rotating shaft is rotatably connected to the rotating seat. Both ends of the rotating shaft protrude from the rotating seat. Through holes are provided on the protruding parts at both ends of the cylinder, and the rotating shaft is connected to the second hydraulic support 5 through the through holes.

[0065] The two ends of the hydraulic cylinder in the middle part of the second hydraulic support member 5 are connected to the rotating shaft through bolts, and the two ends of the rotating shaft are respectively connected to the two rotating seats 4 through bolts.

[0066] The two ends of the hydraulic cylinder are connected to the hydraulic cylinder at one end by a bolt, and a through hole is provided at the other end. The diameter of the through hole is the same as the diameter of the rotating shaft in the rotating seat 4, and can be connected by bolts. After the connection, the hydraulic cylinder can rotate with the axis of the rotating shaft on the rotating seat 4 as the axis.

[0067] The support rod 11 is dumbbell-shaped, tapering in the middle and thickening at both ends. Specifically, it comprises a first convex-shaped structure and a second convex-shaped structure connected by mortise and tenon joints. The thinner end of each convex-shaped structure can pass through the through-holes in the steel plate 9 and the vertical plate, but the thicker end cannot pass through the through-holes in either plate. The thinner end of the first convex-shaped structure is concave, while the thinner end of the second convex-shaped structure is convex. Bolt holes are provided in both the concave and convex portions. The convex portion of the second convex-shaped structure can be inserted into the concave portion of the first convex-shaped structure and secured with bolts.

[0068] The diameter of the spring is larger than the diameter of the thinner part of the convex structure, but smaller than the diameter of the thicker part of the convex structure, so that the spring cannot pass through the two ends of the support rod 11 and can just fit into the middle part of the support rod 11.

[0069] The front and back surfaces of the steel plate 9 are provided with four second through-holes. The diameter of these second through-holes is smaller than the diameter of the thicker portion of the first convex structure, but slightly larger than the diameter of the thinner portion, allowing for the insertion of the thinner portion from the inside out. Three bolt holes are provided on each of the left and right sides of the steel plate 9, from top to bottom, allowing the steel plates 9 on all four sides of the pillar to be connected into a single, square-shaped column using angle plates 7 and bolts. Second grooves are provided at both the upper and lower ends of the steel plate 9 to accommodate the insertion and bolting of the cross-shaped internal reinforcement bracket 1.

[0070] The angle plate 7 has the same height as the steel plate 9 , and the angle plate 7 is provided with a countersunk hole at the same height as the side hole of the steel plate 9 so that the four steel plates 9 can be fixed together through the angle plate 7 using screws.

[0071] The initial length of the first hydraulic support member 6 is the same as the distance between the vertical plate and the steel plate 9, and five first hydraulic support members 6 are grouped together and fixed to an "I" shaped member by bolts. Five circular grooves with the same diameter as the first hydraulic support member 6 are provided at the corresponding positions at the upper and lower ends of the steel plate 9 for the first hydraulic support member to be fixed. "I" shaped grooves are provided on the inner side surfaces of the upper and lower ends of the vertical plate, and a group of prefabricated first hydraulic support members can be fixed to the vertical plate by bolts. Figure 18 As shown, a conduit is connected to the left and right ends of each hydraulic support, and the other end of the conduit is connected one-to-one with the two ends of the second hydraulic support on the same side of the connecting assembly. Specifically, the extension direction end of the first hydraulic support is connected to the shortening direction end of the second hydraulic support through the first conduit, and the shortening direction end of the first hydraulic support is connected to the extension direction end of the second hydraulic support through the second conduit, thereby realizing the hydraulic balance between the first hydraulic support and the second hydraulic support, that is, when the second hydraulic support is compressed, the hydraulic oil pushed out by the piston movement is transported to the extension end of the first hydraulic support through the first conduit, stretching the piston rod in the first hydraulic support from the hydraulic cylinder, and the first hydraulic support as a whole is extended, and vice versa.

[0072] After the two hydraulic supports are installed, when the beam end is subjected to force and displaces downward: the Π-shaped structure at the beam end will rotate downward along the rotating seat 4 in the vertical direction, and the second hydraulic support 5 above the beam will be stretched by the tensile force, and the second hydraulic support 5 below the beam will be contracted by the pressure. At this time, the hydraulic oil pushed out by the extension movement of the piston of the second hydraulic support above the beam is transported to the first hydraulic support 6 above the beam through the second conduit, causing the first hydraulic support 6 above the beam to contract; the hydraulic oil pushed out by the contraction movement of the piston of the second hydraulic support below the beam is transported to the first hydraulic support 6 below the beam through the first conduit, causing the first hydraulic support 6 below the beam to extend; therefore, the angular displacement of the Π-shaped structure 10 will be limited to a certain extent due to the hydraulic balance at the location of the first hydraulic support 6.

[0073] The outer sleeve 3 is sleeved on the outside of the dumbbell-shaped support rod 11 to prevent the dumbbell-shaped support rod 11 from losing its movement space due to the post-cast concrete. One end of the outer sleeve 3 is closed and the other end is open. The opening is provided with a thread and can be connected and fixed with the vertical plate.

[0074] The column end auxiliary connecting sleeve 2 is arranged at the post-casting zone of the column and is connected to the four rotating seats 4 on the column by bolts.

[0075] Each of the four ends of the internal reinforcement bracket 1 is provided with a flange, which can be inserted into the second groove preset in the steel plate 9 and fixed by bolts.

[0076] The installation method of the above-mentioned assembled hydraulic spring flexible shock-absorbing node structure includes the following steps:

[0077] Step 1: Customize the Pi-shaped structure 10 at the beam end, the steel plate 9 at the column edge, the U-shaped steel bar connector 8, the dumbbell-shaped spring connector, the angle plate 7 (for connecting the perforated steel plate at the column edge), the first hydraulic support 6, the second hydraulic support 5, the rotating seat 4, the outer sleeve 3, the auxiliary column end connection sleeve 2, the internal reinforcement bracket 1, 6mm bolts, 10mm bolts, 20mm bolts, springs, and the guide tube 14. Reserve the necessary bolt holes for connection at the corresponding locations of the various steel plates and connectors.

[0078] Step 2: Connect the four hole-punched steel plates 9 on the four column sides to the four angle plates 7 in pairs with bolts;

[0079] Step 3: Fix the five first hydraulic supports 6 on an I-shaped component, and fix the I-shaped component to the vertical plate at the end of the beam by bolts.

[0080] Step 4: Insert half of the dumbbell-shaped spring connector through each circular hole on the perforated steel plate at the column edge, placing the larger end of the dumbbell-shaped spring connector inside the column. Insert the spring into the other half of the dumbbell-shaped spring connector, and then insert this dumbbell-shaped spring connector through each circular hole of the vertical plate of the Π-shaped structure 10 at the beam end. At this point, the connected portion of the two halves of the dumbbell-shaped spring connector is located between the steel plate 9 at the column edge and the Π-shaped structure 10 at the beam end. Align the first hydraulic support 6 with the groove of the steel plate 9 at the column edge, insert the other spring into the dumbbell-shaped spring connector portion between the two plates, and connect each half of the dumbbell-shaped spring connector together with bolts.

[0081] Step 5: Insert the cross-shaped support into the ⊥-shaped groove of the steel plate 9 on the side of the column and fix it with bolts;

[0082] Step 6: Put the outer sleeve 3 on the dumbbell-shaped spring connector and fix it to the Π-shaped structure 10 at the beam end with bolts;

[0083] Step 7: Place each U-shaped steel bar connector 8 in the vertical groove of the Π-shaped structure 10 at the beam end and fix them respectively with bolts;

[0084] Step 8: Bolt the rectangular plate of the rotating base 4 to the upper and lower crossbars of the Pi-shaped structure 10 at the beam end. Insert the end of the second hydraulic support 5 through a hole in the cylindrical portion of the rotating base 4 and secure it with bolts. The other end of the second hydraulic support 5 is assembled in the same manner, but the rectangular plate at this end is bolted to the octagonal support placed in the post-casting zone.

[0085] Step 9: Make the whole device in normal state, and cast concrete in the column post-casting zone. After the concrete strength reaches the requirement, insert the longitudinal reinforcement extending from the precast beam into the U-shaped steel bar connector 8 of the Π-shaped structure 10, and bend it manually. Finally, cast concrete in the beam post-casting zone.

[0086] Step 10: After the strength of the cast-in-place concrete reaches the required level, connect the conduit to the first hydraulic support 6 and the second hydraulic support 5.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application.
